Get a Remote File's Creation Time

See more SFTP Examples

Demonstrates the Chilkat SFtp.GetFileCreateTimeStr method, which returns a remote file's creation date and time. The arguments are the remote path (or handle), whether symbolic links are followed, and whether the first argument is a handle.

  // links are followed, and the 3rd indicates whether the 1st argument is a handle.
